Established in 1976 Plumpton High School is a large multicultural 7-12 secondary school. The School Mission Statement, "Plumpton High School puts students first", is central to the whole school philosophy. In its aim to develop higher level skills in literacy and numeracy the school allocates hours in Years 7-10 above the minimum requirements in the core subjects of English, maths and science. In the senior school the curriculum is very broad with the school offering a wide choice of academic and school and TAFE delivered vocational courses.
A number of HSC pathways are available which lead to university, TAFE or the workplace. Some students complete their HSC over two or more years and the school has a number of mature age students.
